API issue with importing from simPRO to MYOB AR

Hi, is anyone else having issues connecting simPRO to MYOB AR?

I had a pop up message about MYOB requires Admin Access to connect the files as of September 1st but it wants to do it today and when I try to connect all I get is an error message saying "Something went wrong and we couldn't connect the app. Try again later."

This is right on month end, the worst possible time for it to happen, we push multiple times a day and I can't even do one.  We have 15 company files and I have tried for about 4 of them and none are connecting.

I am an Online Administrator and I have Administrator User Access in the files.

We have successfully connected other software due to the same MYOB requirements without an issue. 

I have checked the MYOB status page and it shows that all services are "UP" but does show the below message so thinking maybe something has gone wrong??

We will be performing planned maintenance on our login services for a small subset of customers.

I called the 0800 support number but they just pushed me to log a developer ticket which didn't make sense since I'm not a developer.

Can someone from MYOB please help.

Thanks Natasha
